Sitting at a desk in a classroom all day can be pretty boring.
The teachers at Ward Elementary in Winston –Salem, North Carolina, picked up on that and traded in their students’ desks for exercise bikes as a part of their Read and Ride program!
The Read and Ride program began five years ago．One classroom has enough bikes for every student in any given class, and throughout the day teachers bring in their students to the room to ride them and read their books．
Even regular classrooms have one bike in the back of each room for students who just can’t sit still to use to help them burn energy in a good way．
Students love being more active! Teachers enjoy seeing students eager to read． Parents appreciate stronger, smarter children．Headmasters value this effective and cost-free program．“Riding exercise bikes makes reading fun for many kids who get frustrated(挫败的) when they read． Thus, they have a way to release that frustration while they ride,” said Scott Ertl, who started the program．“As we can see, everyone wants to promote literacy and lose weight! But many students who are overweight struggle with sports and activities since they don’t want to always be the last or lose with others watching on the playground． On exercise bikes, however, students are able to exert(发挥)themselves at their own level—without anyone noticing when they slow down or take a break.”
As it turns out, not only are the bikes helping the students burn calories, they’re also helping them learn better and stay focused． At the end of the school year the school analyzed testing data and found that students that spent more time reading and riding did more than twice as well on reading tests than their fellow students who spent the least time in the program.

What separates me from everyone else? The difference is not what clothes I wear or the music I listen to, but what I feel inside．
Ever since I was young, I have loved professional wrestling．I woke up every Saturday to watch my favorite "Superstars．" As I grew older, I got a lot of flak for watching this "fake" sport．My peers would laugh at me for following what was called a "man's soap opera．" So, I put my love for wrestling on the shelf．Like everyone else, I wanted to be associated with the cool clique．I yearned to be invited to the parties of the in-crowd and hang out with the popular kids．I became pretty successful．Although my Friday evenings were busy with parties, I would still wake up early Saturdays to watch wrestling．It wasn't until freshman year that I realized I wasn't being myself．
That year, I tried many new things and activities and made new friends．In my town, football was the sport, so I decided to play football, thinking it might give me a head start in popularity．The team started with 48 athletes．At the end, there were 14 of us left．I stuck it out not because I liked it, but because I am not a quitter．That long season taught me a lesson: I wasn't a football player．More importantly, it taught me to be myself．
After that season, I went back to being a wrestling fan．I watched it religiously, no matter what insults were thrown my way．I came across a quote: "Don't Dream It, Be It．" When I read this, my friend Dan had the same idea I had．
"What if we build a wrestling ring?" we asked．We acquired the necessary wood and equipment for its construction．The following weekend, we met at his house．We saw our dream in a pile in his backyard．We worked from dawn to dusk to build our great establishment．By Sunday night, our mission was complete．Our hard work (combined with a little creativity) had paid off．We had a real ring．We decided to hold an "event．" We practiced for hours, trying to improve every aspect of our wrestling ability．The date was May 24th．Our show had a start time of 9: 00 p．m．To our surprise, about one hundred family, friends and fans showed up to support us．It was the most important night of my life and a complete success．Since that time, we have held five shows with as many as two hundred and fifty people turning out．We continue to live this dream．We accomplished what we set out to do．We are now well known throughout school．When I walk down the halls, I am respected by my peers．Some are the same peers who ridiculed me for watching wrestling when I was younger．When they approach me, they often say, "Good match, Chris．" I humbly say, "Thank you," knowing I did something I believed in．
As my senior year winds down, I'll remember all of my high school memories．But what will stick out most is the memory that I did something I loved, despite what everyone said or thought．I accomplished my goal ．．．I lived my dream．

In Shanghai's Grand Theater, a fashionable, mainly young audience applauds enthusiastically as Guo Yong takes center stage．He holds a large bushy tree branch with leaves．Blowing on one of the leaves, he produces a sound like the singing of birds as he plays a traditional Buyi folk song．Some other musicians are also playing the traditional instruments from various ethnic groups in China．
It's the first time such music has ever been performed in the Grand Theater．But all this is the efforts of Zhu Zheqin, a Cantoneseborn singer, who has made it her mission to help preserve China's traditional ethnic music．
In 2009, after being appointed a United Nations Development Program ambassador, Zhu traveled through some of China's remotest regions in an attempt to document the traditional music of various minority groups．In the course of the fourmonth trip, she recorded more than a thousand songs．But she noticed that many of the best musicians were old, and some of the music was at risk of dying out．
“I was shocked by the beauty of what I heard—it was so good，” she says．“But it needed support．I hope to let people see the beauty of these things in the contemporary times．”
So Zhu decided to introduce some of the musicians to a wider audience．By doing this, she hopes to rekindle(点燃) the interest of the younger generation．“Young people don't like this music much; they prefer pop music and love songs．They think these songs are something their grandma sings．This kind of repackaging gives young people a new door into their heritage．”
Zhu believes China needs to look again at its own roots．“China today is basically all Western art; in our conservatories (音乐学院) Western classical music is the top，” she says．“For China to really contribute to the world, we need to go on our own path．So what can represent China today？” The answer, she suggests, is to move from “made in China” to “created in China”．
From the first paragraph, we learn that________．

A．the audience are all young people

B．Guo Yong is playing the Buyi folk music

C．Guo Yong is the only minority performer in China

D．tree branches make good musical instruments

Which of the following is true of Zhu Zheqin?

A．She teaches music in a conservatory．

B．She is helping preserve Chinese ethnic music．

C．She works as an official in the United Nations．

D．She's created all the music for the Grand Theater．

What is Zhu Zheqin's idea about Chinese traditional music?

A．It is completely out of date．

B．Only old musicians play it well．

C．It needs changes to attract young people．

D．It is quickly dying out．

What does Zhu Zheqin mean in the last paragraph?

A．The traditional music should be repackaged．

B．Chinese conservatories shouldn't teach Western music．

C．China has contributed a lot to the Western art．

D．Only the things created in China can be symbols of China．

In 1693 the philosopher John Locke warned that children should not be given too much “unhealthy fruit” to eat．Three centuries later, misguided ideas about child-raising are still popular．Many parents fear that their children will die unless ceaselessly watched．In America the law can be equally paranoid (偏执的)．In South Carolina this month Debra Harrell was jailed for letting her 9-year-old daughter play in a park unsupervised (无人监督的)．
Her severe punishment reflects the rich world’s worry about parenting．By most objective measures, modern parents are far more conscientious (认真的) than previous generations．Dads are more hands-on than their fathers were, and working mothers spend more time nurturing their children than the housewives of the 1960s did．However, there are two problems in this picture, connected to class．One is at the lower end．Even if poor parents spend more time with their children than they once did, they spend less than rich parents do．America is a laggard here: its government spends abundantly on school-age kids but much less than other rich countries on the first two or three years of life．If America did more to help poor parents with young children, it would have huge returns．
The second one, occurs at the other end of the income scale, and may even apply to otherwise rational (理性的) Economist readers: well-educated, rich parents try to do too much．Safety is part of it—they fear that if they are not constantly watching their children may break their necks, which is the least rational．Despite the impression you get from watching crime dramas, children in rich countries are safe, so long as they look both ways before crossing the road．The other popular parental fear—that your children might not get into an Ivy League college—is more rational．Academic success matters more than ever before．But beyond a certain point, parenting makes less difference than many parents imagine．Studies in Minnesota and Sweden, for example, found that identical twins grew up equally intelligent whether they were raised together or apart．A study in Colorado found that children that adopted and raised by brainy parents ended up no brainier than those adopted by average parents．
This doesn’t mean that parenting is irrelevant．The families who adopt children are carefully screened, so they tend to be warm, capable and middle-class．But the twin and adoption studies indicate that any child given a loving home and adequate stimulation is likely to fulfill her potential．Put another way, better-off parents can afford to relax a bit．And if you are less stressed, your children will appreciate it, even if you still make them eat their fruit and vegetables．
Which of the following statements is NOT a misguided idea of parenting mentioned in the passage?

A．Children should be protected from any dangers by their parents

B．The more conscientious parents are, the more children will surely benefit from parenting

C．Children will die unless ceaselessly watched

D．Children are likely to fulfill their potential with a loving home and adequate stimulation

The underlined word “laggard” in Paragraph 2 probably means a country that __________．

A．is ahead in development

B．falls slow behind others

C．is free from physical or mental disorder

D．moves to a higher position

Which of the following can we learn from the passage?

A．Only warm, capable and middle-class people can adopt a child．

B．When it comes to child-raising, Economist readers will become more rational．

C．Children in rich countries are in greater danger due to the bad influence of crime dramas．

D．Although poor parents spend more time with their kids than they once did, they spend less than rich parents do．

This passage is mainly written to __________．

A．urge American laws concerning parenting to be changed

B．advise modern parents to learn from their previous generations

C．persuade stressed parents to learn to relax and give more freedom to their children

D．call on the government to do more to help poor parents with school-age children
